Conduct the following test at the α=0.10level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling.Test whether p1≠p2 Sample data are x1=28, n1=254, x2=38, and n2=301.

(a) Determine the null and alternative hypotheses. Choose the correct answer below.

A. H0: p1=p2 versus H1: p1>p2

B. H0: p1=p2 versus H1: p1≠p2

C. H0: p1=0 versus H1: p1=0

D. H0: p1=p2 versus H1: p1<p2

(b) The test statistic z0
is _____?
(Round to two decimal places as needed.)

_____?

(Round to three decimal places as needed.)

Test the null hypothesis. Choose the correct conclusion below.

A. Reject the null hypothesis because there is sufficient evidence to conclude that p1≠p2.

B.Reject the null hypothesis because there is not sufficient evidence to conclude that p1<p2.

C. Do not reject the null hypothesis because there is sufficient evidence to conclude that p1>p2.

D. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p1≠p2.
